Torn between shame and forbidden desire, a married woman fulfills her husband's cuckolding fantasy by joining a partner-swapping club. Reuniting with M-mi as "36," she is given the extreme condition of performing sexual acts in front of her husband. Hesitant at first, her body betrays her as she gushes lubrication and writhes in ecstasy. Pounded by a man's cock, she repeatedly climaxes under her husband's gaze. Pushed to the limit, she performs masturbation with a vibrator while giving blowjobs to another man. Her husband joins in, and she is overwhelmed by two male members. As her reason collapses, the married woman drowns in pleasure, orgasming again and again.
